Application filed May 23,

' To all whom it may concern: I Be it known that I, WILLIAM F. GROENE, a citizen of the United States ofAmerica, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented a new-and useful Improvement in a Combined Brake and Clutch Device, of which the following is a specification. My invention relates to devices of the type disclosed in my Patent No. 1,474,112.

An object of my invention is to provide a simple structure for providing a relatively large frictional face for effecting prompt and efficient braking action.

These andother objects are attained by r the means described herein-and disclosed in the accompanyin drawings, in which:

Fi 1 is a sectional view through a combine braking clutch 1 structure embodying my invention. i

Fig. 2 is a sectional view on line 2-2 of Fig. 1 showing a friction cone forming part of my invention, V

Fig. 3 is an elevational view on line 33 of Fig. 1, parts beingbroken away. 1

Fig. 4 is an enlar ed view of a friction cone forming a detai of my invention.

" of the structure shown in upon shaft 12 and which is pinned .to the shift rod 13 by means of the pin 16, all of which is in accordance with the neral practice in. the art. The housing 10 as secured upon it a block 17 by any suitable. means such as bolts 18 and the block 17 is provided with a borewithin which is dis-.

posed a sleeve 19 that serves as a bearing for the shaft 12. The block 17 carries a sleeve like extension 20' that serves as a bearing for the pulley 21. Thepulley 21' carries. an end cap 22 that controls access to the various elements di osed at the end ig. 1. The pul- 23 formedon it,

tion collar 25 and the friction plate 26. The friction collar and the. friction plate. are

adapted to revolve with the shaft 12. 'Be- The lever 28 carries a roller 31 that is engaged by the rod 13. From the foregoing it will be evident that if the rod 13 be moved toward the right, see Fig. 1', the action thereof resolves, itself into a movement of the friction collar and friction plate such that said collar and plate bind the friction.

rings 27 and the toothed rings 24 so that mption is transmitted between the pulley 21 and the shaft 12. The sleeve like extension 20 is provided at its end with lugs 32 that lodge in extensions 320 of aperture or bore 33 formed in the central or hub portion of the brake cone 34. The cone 34 is provided with an extended external conical face 35 upon which the internal conical face 3'3 of the friction collar 25 may engage. Springs 37 yieldingly resist compression action of the friction collar and friction plate and also yielding'ly retain the conical face of the friction collar in enga ement upon the conical face 35 of the iction cone 34.

It has been explained how motion is transmitted between the pulley 21 and the shaft 12. When the shift rod 13 is moved toward the left, see Fig. 1, the springs 37 move the' friction collar and friction plate apart so that the driving connection .be-

tween the pulley and the shaft is severed while at the same time the friction collar is moved into braking engagement with the cone 34. i

WhatI claim is: i 1. In a combined clutch and brake mechanism the combination with a'-driven;.shaft,

and into clamping engagement upon' the friction rings, a sleeve associated with the driven shaft and a brake disc mounted on the sleeve and provided with a conical friction face disposed radially outward from the sleeve and upon which face the friction collar may engage when the clamping engagement is broken.

2. In a combined brake and clutch mechanism the combination with a driven shaft, of a pulley mounted concentrically with the driven shaft, friction rings mounted-on the drive pulley, a friction collar and a friction plate on the driven shaft adapted to be clamped upon the friction rings, a brake -sleeve mounted upon the driven shaft and fixedly mounted on the machine to which the mechanism is applied, the brake sleeve being provided with lugs at its one end, a brake disc provided with apertures for receiving the lugs on the brake sleeve and having a friction face disposed radially outward from the brake sleeve and upon which friction face the friction collar may en age, and means adapted to mormally hol the nism the combination with a driven shaft,

vided at its one end with radially extending lugs, a friction disc having a central aperture with radial extensions for the reception of'the radially extending lugs on the brake sleeve, a drive pulley mounted on the brake sleeve, a friction collar reciprocally mounted upon the driven shaft and extending over the friction disc and adapted to engage the friction disc, means to normally hold the friction collar in engagement with the friction disc and means to release the friction collar from the friction disc and to move it into engagement with the drive pulley.

of a fixed brake sleeve mounted concentric to the driven shaft, the brake sleeve pro- In testimony whereof, I have hereunto subscribed my name this 12th day of May, 1924.
